The Teen Mom 2 star’s comments came after a fan tried taunting him with a photo of Lowry, 25, posing at a recent book signing with two fans wearing “Team Javi Puta” shirts. “Look you made it to ex wifey’s book signing @Javimarroquin9,” the user wrote.

Marroquin, 24, wasn’t too bothered by the picture. “Their shirts are epic,” he replied, seemingly laughing off the women’s attire. In a second tweet, he added, “At the end of the day that isn’t cool. That’s my sons mother. We’ve put everything behind us to raise our son the right way.”

Lowry, meanwhile, recently announced that she is pregnant with her third child, though she has yet to name the father. “I know this isn’t an ideal situation but I know everything will be okay,” the 16 and Pregnant alum, who is also mom of 7-year-old son Isaac with ex Jo Rivera, wrote in a blog post on February 24.
